Stair lifts can be configured to handle any staircase. Most staircases are either straight, have a middle landing, or are curved/spiral. In some cases, a customer who has a middle landing can put 2 stair lifts in, one on the first set of steps and the other on the second set.

Not really, unless you don't have an electrical outlet to support the operation of the stair lift. In this case, you would need an electrician to install an outlet before the stair lift is installed. In some cases, the stair rail might need to be removed if it obstructs the operation of the stair lift.

An A/C unit is operated from the standard household outlet. If the electricity goes out, the stair lift will not operate. There are no ongoing costs to support the operation of this unit like there are with the BOS.

A BOS (Battery Operated System) is operated by standard 12V batteries. The BOS will operate if there is an electrical power failure for as long as the batteries last (typically 10 trips). Batteries for these lifts need to be changed annually. Typical cost for 12V batteries are $50-$75. 12V batteries are similar to those that operate children's Barbie or play cars driven on driveways.

Stair lifts can be useful even for someone who has limited mobility. Convenience features built into some models include folding arms that push up and out of the way, adjustable seat heights, and soft, padded seats.

Key safety features on most stair lifts include a seat belt, obstruction sensors that will stop the lift should something block its path, a swivel seat lock that holds the unit in place while you get on or off. Constant pressure controls ensure the lift will stop if you release your finger from the controls.
